TYPES OF NETWORKS (Lesson 70)

Three types of networks:
  •  Local Area Network or LAN
  •  Metropolitan Area Network or MAN
  •  Wide Area Network or WAN
Here:
  •  LAN - the email system within the school lab in SMK KL
  •  MAN - the email system within KL city
  •  WAN - the email system between KL and London
A LAN covers a small region of space, typically a single building.
A MAN is a collection of LANs with the same geographical area, for instance a city.
A WAN can be a collection of LANs or MANs or the mix of two with a very large geographical area, for instance a country or even beyond the border.
